Answer:
An equation represents the number of pieces of lasagna that are left after dinner is ![\frac{1}{6}x=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7Dx%3D%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
Each piece of Lasagna is 1/6 of the pan
Let x be the number of pieces left
So, x pieces is
of the pan
We are given that After dinner 2/3 of a pan of lasagna is left.
So, ![\frac{1}{6}x=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7Dx%3D%5Cfrac%7B2%7D%7B3%7D)
![x=\frac{2}{3} \times 6](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B3%7D%20%5Ctimes%206)
x=4
So, Number of pieces left = 4
Hence An equation represents the number of pieces of lasagna that are left after dinner is ![\frac{1}{6}x=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7Dx%3D%5Cfrac%7B2%7D%7B3%7D)
Answer:
Answers: 1) gh= -7×3= -21
2) g2-h= -7×2-3= -17 *that is what I got from my calculations.
3) g+ h2 = -7+3×2= 1 *that is what I got from my calculations.
4) g+h = -7+3 = -4
5) h-g= 3--7= 3+7= 10
6) g-h= -7-3= 10
Step-by-step explanation:
I don't fully understand neither but I tried.
Answer:
-0.899
Step-by-step explanation:
In the 4th quadrant, the sine is negative and the cosine is positive. The sine is ...
sin(-arccos(0.437)) ≈ -0.899
_____
You can also use the trig identity ...
sin(x) = -√(1 -cos(x)²) = -√(1 -.190969) = -√.809031 ≈ -0.89946150557
The sine is about -0.899.
